    Steel or Iron

    SampleProductDescription
    Black Oxide Black Oxide Room temperature blackener for Steel & Iron. Seal with Penetrating Sealer for oily finish, or Caswell Sealer for dry finish

    Stainless Steel

    SampleProductDescription
      Stainless Steel Blackener Room Temperature Blackener for stainless steel. Seal with Caswell Sealer for extra protection

    Copper

    SampleProductDescription
    Tiffany Green Tiffany Green Gives a pleasing Tiffany Green affect on copper parts.
    Bronze & Blackening Solution Bronze & Blackening Solution Gives a bronze to black color on copper and silver parts.
    A311 - Flemish Gray & Blackener A311 - Flemish Gray & Blackener Used at 15% to 20% by volume solutions produce black to blackish-brown US 10B finishes on copper and brass with immersions of 1 to 3 minutes. Diluted 5% to 10% by volume solutions produce lighter finish and statuary bronzes with 1 to 3 minutes of immersion. Desirable underlying red tones revealed upon highlighting the brown tones.
    A312 - Chocolate Brown A312 - Chocolate Brown Used at 20% by volume solutions produce more pronounced brown to chocolate brown colors on copper and brass than 311, with a richer reddish tone when highlighted. 1 to 3 minute immersions. Diluted 5% to 10% by volume solutions produce very light brown tones.
    A313 - Black & Brown Oxidizer A313 - Black & Brown Oxidizer Used at the same dilution as 311 and 312 with copper and brass, but the highlighted finishes do not exhibit any underlying red tones. It is also used to blacken Silver and Nickel.
    A316 - Verde Green A316 - Verde Green Used full strength or diluted with water to produce a natural verdi or patina green or bluish color on copper alloys. The natural looking finishes are produced by first treating the copper or brass surfaces with A311 to produce a brown finish. The subsequent A316 finish will adhere better to the brown finish than it will to bare copper or brass surfaces.
    A324 - Swab On Copper Blackener A324 - Swab On Copper Blackener An instant-acting swab-on/touch-up chemical conversion finish for copper and its alloys. The color produced can be varied from light brown to brown to black.
    A327 - Gun Metal Blue A327 - Gun Metal Blue Diluted with water and used at room temperature as an immersion “oxidizing” solution. Produces gun metal blue, black, brown and slight purple on copper, brass, bronze, white metals, silver and tin lead alloys. These colors are dependent upon substrate, immersion time and concentration. Used at 10-50% by volume at 65-85° F. Does not contain selenium.

    Aluminum

    SampleProductDescription
      A385 - Aluminum Blackener
    The A385 liquid concentrate is diluted with water and used as an immersion blackening solution for aluminum and its alloys. Used full strength, the concentrate may be applied by swab-on techniques for blackening engravings, etchings, prototype parts or for the quick touch-up of scratched or re-machined black anodized surfaces. The black finishes are of negligible thickness. Therefore, they produce essentially no dimensional changes in the finished part.
    Use A385 anywhere. No special equipment, control procedures, ventilation or heating.
    Vary color from rich pewter gray to deep black by dilution and dwell time. Results are uniform, consistent, repeatable...stable under lacquer...colorfast through age or sunlight. Leave finish jet black to replace anodizing...or relieve and highlight to simulate pewter. Seal or lacquer for added richness and abrasion resistance. A385 blackens castings that cannot be anodized. It can replace anodizing where metal-against-metal abrasion resistance is not required. A385 is a non-caustic, odorless preparation of mild, water-soluble chemicals.
    Alodine 1201 Alodine 1201
    Nonflammable, chromic acid-based, coating chemical that will produce a chrome conversion coating on aluminum and its alloys. The coating formed by Alodine® 1201™ is gold to tan in color and it becomes a part of the aluminum surface. This chrome conversion coating offers the best affordable substrate for both paint adhesion and corrosion resistance. Can be applied by brush or immersion. For immersion use, dilute 30% Alodine 1201 to 70% water. Use at room temperature. 1 Quart treats approx 100 sq ft

    Tin/Pewter

    SampleProductDescription
